摘要 目的评估糖化血清蛋白(GA)和糖化血红蛋白(HbA1c)检测在糖尿病诊断中的应用价值。方法该院内分泌科收治的糖尿病患者224例纳入糖尿病组,并选取238例健康人纳入对照组。2组研究对象均行口服葡萄糖耐量试验(OGTT)、GA、HbA1c检测,结果进行比较,并应用受试者工作特征(ROC)曲线评价二者对糖尿病的诊断性能。结果糖尿病组的OGTT、GA、HbA1c检测结果均高于对照组,差异均有统计学意义(P<0.05)。糖尿病组的HbA1c与空腹血糖(FPG)、2h血糖均呈正相关(r=0.516、0.427,P<0.05);GA与FPG、2h血糖呈正相关(r=0.527、0.449,P<0.05);FPG与2h血糖呈显著正相关(r=0.462,P<0.05);HbA1c与GA呈显著正相关(r=0.884,P<0.05)。GA敏感度(85%)高于HbA1c敏感度(76%);HbA1c特异度(83%)高于GA特异度(75%)。GA、HbA1c与OGTT联合作ROC曲线,GA和HbA1c敏感度、特异度和预测概率分别为76%、72%、78%,71%、77%、81%;二者联合检测的敏感度、特异度、预测概率分别为77%、77%、76%。结论 GA和HbA1c联合检测在糖尿病诊断中具有重要的应用价值。
